MACHINE FOR BLEAGHING AND DYEING- FABRICS.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed November 1, 1907. Serial No. @00242.

To all whom it may concern:

Be it known that I, GEORGE COLLIs, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in Machines for Bleachingand Dyeing Fabrics; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements in the artof treating fabrics with liquids and more specifically to a machine forbleaching and dyeing goods of various character.

ln machines heretofore constructed for similar purposes, one of the mainobjections has been that there has been occasioned a very large andconstant leakage of the dyestuff, which has not only been a source ofdisadvantage to the process, but has involved a considerable financialloss. A further objection has been that when one batch of goods has beenacted on, the dye-stuff is not put to any further use until the goodsare re moved and others substituted, thereby entailing great loss oftime. In order to overcome this as well as other bad features ofmachines used at present, I have designed this machine, which is soconstructed that there is no leakage whatsoever of the dyeing materials,and furthermore the arrangement is such that in a machine of the samesize as those now manufactured, a much larger amount of dyeingsubstances can be applied to the same mass of goods, hence securing amore complete action in quicker time.

A further object to be attained by my invention resides in the fact thatI arrange my machines in pairs, with means between them for forcing theliquid from one to the other. It will be clearly evident, therefore,that when the dyeing of the goods in one machine is completed, theliquid may be forced therefrom to the other machine, which has in themeantime been filled with goods to be treated, and the goods then takenfrom the first ma chine and a fresh supply substituted, after which thedye stuff or other material is forced back again and so on indefinitelyIn this way, the full benefit of the dyeing substance is obtained bycontinual use.

These and other advantages will appear from the following detaileddescription when read in connection with the accompanying drawings, inwhich- Figure l is perspective view of a single machine, showing partsbroken away, Fig. 2 is a side elevation of a pair of my machinesassembled for operation, Fig. is a vertical section on the line a -a ofFig. 1, and Fig. f is a transverse section through the interior screenshowing the end in elevation.

Referring more specifically to the drawings in which like referencecharacters refer to corresponidng parts in the several views, Adesignates a cylinder preferably of metal, and supported on the legs B,said cylinder constituting a dyeing chamber into which the goods to betreated are introduced through the door C, occupying substantiallyonefourth the circumference of the cylinder. Within the cylinder, andsuitably supported therein is a wire or perforated metal cloth cylinderD, provided with a hinged door L, and carrying at its one end the largegear E, adapted to mesh with the smaller gear F hereinafter to bereferred to. The supports for cylinder D herein shown, comprises ournalsI), provided with roller bearings and closed by a cap plate 0. Theroller bearings are employed as a substitute for the usual lubricationwhich is disastrous to a dyeingor similar process. It is to beunderstood, however, that the particular form or position of bearing isimmaterial as it may just as well be placed inside the end plate of thecylinder, leaving a smooth exterior surface, or changed in any othersimilar manner without departing from the essential idea hereindisclosed. T he cylinder D includes a frame comprising bars at runninglongitudinally of the cylinder and extending transversely of the endsthereof. Secured to the bars (2, both on the sides and ends of tnecylinder are paddles or vanes c, which project a slight distance fromthe walls of the cylinder and assist materially in agitating the goodscontained within the cylinder, during rotation of the same.

Supported on the end of the cylinder A by a suitable bracket is anoperating and reversing mechanism M, which may comprise any well knownconstruction, the details thereof constituting no part of my invention.This gearing includes a shaft f carrying at its end the before mentionedgear F. An opening I is formed in the top of the cylinder A and thepositioning of the arts is such that the gear F projects througi saidopening and is arranged to mesh with gear E, serving to revolve the samewhen the mechanism M is set in operation.

In machines, heretofore constructed for a similar purpose, it hasgenerally been pro posed to support the interior cylinder on a shaftextending through the stationary cylinder and carrying a gear wheel atits outer end, exterior to the said stationary cylinder. The operatingmechanism was placed lower down to enable the smaller gear, which is Fof the present construction, to properly mesh with the gear of theaforesaid shaft, but the construction is open toserious objectionsbecause it enables the dyeing liquid to be used in the cylinder only toa depth indicated by h on the drawings. If the liquid was filled in upto a point such as k, a severe leakage takes p ace through the cylinderat the opening through which the shaft of the wire cylinder passes. Bymy construction, however, this is entirely obviated, as the cylinder isentirely closed at all points except on the top, and the dye-stud may befilled as high as is ever dc manded without a )article of loss. theemployment 0 roller bearings, I am enabled to do away with the use ofany lubricant which gets into the dyeing substance and injures itmaterially.

Referring now more particularly to Fig. 2, I show here two machinesarranged side by side with a pump K situated between. Connections m areformed on the bottom of cylinders A, and suitable couplings n join themto the pipe which constitutes a passage from the cy inders A to the pumpK.- Valves 8, s 8 s are suitably located in the pipe p and when desired,they may be proper y manipulated to permit the waste liquid Also, by

to be drawn or forced out from both cyline ders through either of thebranches g.

Various changes and modifications will suggest themselves to any oneunderstanding my invention, but it is to be understood that alterationsmay be made without departing from the spirit thereof.

hat I claim, and desire to secure by Letters Patent is:

1. A machine for bleaching and dyeing fabrics including a closedcylindrical receptacle, a hinged cover for said receptacle, an openingadjacent the cover, a perforated cylindrical receptacle supported withinthe first -mentioned receptacle, and having a frame including agear-wheel, vanes or paddles arranged radially of said gear-wheel andlongitudinally of the sides of the perforated receptacle, a pinionpositioned in the aforesaid opemng and engaging said gear-wheel, andmeans for rotating the p nion.

2. A machine for bleaching and dyeing fabrics including a closedcylindrical receptacle, a hinged cover for said receptacle, an openingadjacent the cover, a perforated cylindrical receptacle, journalbearings for supporting the same, detachable plates for closing theouter ends of said journal bearings, a frame for the perforatedreceptacle including a gear-wheel, vanes or paddles arranged radially ofsaid gear-wheel and longitudinally of the sides of the perforatedreceptacle, a pinion positioned in the aforesaid openin and engagingsaid gear-wheel, and means for rotating the pinion.

In testimony whereof, I affix my signature, in the presence of twosubscribing witnesses.
